A virgin prince no longer

Marcus opened his mouth to speak, to tell his sister not to do this. In that moment, Jenny lowered herself down the last few inches. The young prince's voice died in a strangled moan as he felt his little cock slip into her warm, wet pussy. This was...amazing! It felt so much better than her hand! Every inch of his dick was rubbing against her skin, hot and silky soft. His hips trembled and before he could think he started trying to buck them up against her weight. She was resting on him and he could hardly move, but even the small amount he could shift his cock inside her felt like heaven.

"Fuck." Jenny breathed, her lips wet and parted. "You feel so good inside me, little brother." Her eyes flickered back to his face, dull and hungry. She started grinding herself against his body, pressing herself down and forward at the same time. Each time she moved his dick rubbed back and forth inside her, gliding deeper into the hot warmth of her pussy. It felt so good he couldn't even think why he hadn't wanted this at all.

"Jenny..." Marcus gasped. He was lying back against the bed, limp and trembling. She rode him hard, pressing him down into the blankets with her weight. He couldn't do anything. She was just using him, taking her pleasure from his willing body. Even that thought made him flush even hotter and moan softly as naughty tingles tickled over his skin.

"You're mine, runt." She growled again, and suddenly she lent all the way forward, her body pressing down against his. He could feel her soft boobs on his chest through the covering of his tunic. Her lips found his and she kissed him hungrily, still grinding his cock deeper inside her with her muscled hips. "Mine." She breathed in his ear. Marcus moaned, biting his lip as her hot breath tickled over his skin.

She was kissing his neck now, her teeth nibbling at him like she was some vicious lioness devouring her prey. All these naughty thoughts and naughty things she was doing filled his head with heat. His whole body trembled, his muscles tensing then relaxing at the waves of pleasure flooding through his core. Her hips bounced, as she slammed her pussy down into him with all her weight, again and again burying him to the hilt.

The smack of her skin on his filled his ears, her muscles rubbing against the softness of his thighs. It was all too much for a prince who'd only ever felt his own clumsy fingers down there before. In moments, he let out a high-pitched gasp, white-hot sparks flooding up his shaft. He felt the sticky wetness as he spurted into his older sister's pussy. He trembled like a leaf, his muscles bucking up against her weight without him even thinking about it.

Jenny moaned in satisfaction, grinding her hips from side to side like she was trying to wring the last of his seed out of him. Marcus was still shivering underneath her. It had felt so very good, but now as the fuzzy haze of pleasure slipped away he suddenly realized what he'd just done and felt a cold chill replace it. He'd just...lost his purity, been deflowered by his own sister! Oh...no, his parents! What would they think? His Mother would be furious with him! She was always warning him to save himself for his wife!

"That felt good, little brother." Jenny moaned on top of him, her voice trembling with satisfaction. "You didn't finish me off, but we've got all night to fix that." She lent down and kissed him on the forehead, then on his cheek, her lips moving down until they found his. He lay back as her tongue slipped between his teeth, giving him another of those hungry, naughty kisses that made him blush. "I'll have to train you to last longer next time." She breathed as she withdrew. "You're kind of small down there, so you've got to work harder to please me. Maybe we can use this pretty little tongue of yours too. Get you kneeling between my legs, licking my cunt. Now that's a delicious thought."

"Jenny..." Marcus whimpered, finally finding the strength to speak. "We shouldn't have done that."

"Why not?" His older sister sighed, her eyes still glazed with that same hungry look.

"It's...we're siblings." The young prince stammered. She cocked her head, like she had no idea why that would even be a problem. "I'm supposed to be pure for my wife." Marcus continued, desperately searching for a way to make her understand. "Mother was always telling me that..."

"Mother?" Jenny froze on top of him, her muscles tense against his soft naked body. Then her lips curled, and when she spoke again her voice trembled with vicious frustration. "That bitch. I should have known. She...got to you first, did she? Fucking whore! I'll have her head!" She sat up on top of him, glaring down with narrowed eyes, her chest heaving with each hot breath.

"No!" Marcus gasped, staring up at his furious sister in horror. Not their Mother! "She just warned me not to do this until I was married!" Jenny paused, her brow furrowing. Some of the wild anger eased from her eyes, and for a moment he thought she might actually be calming down. Then she laughed, high and cold, just the sound sending shivers down his spine.

"Mother told you that?" She chuckled cruelly. "I can guess why. She wanted you saving yourself for her! I saw the way she used to stare at you when we were kids. She wanted you, just as much as I did! Fucking cunt! Well, it's too late now. You're mine, little brother. I took your first time, not her! She's never getting another sniff at you!" She smirked in triumph, then suddenly she started grinding against him again, rubbing her pussy against his pelvis. Marcus whimpered as he felt his still sensitive dick rubbing against her. It felt really uncomfortable this soon, but he knew begging her to stop would get him nowhere. "Let's get you hard again, runt." She purred, biting her lip in satisfaction. "I want a couple more of your loads inside me at least tonight."
